OK, you are searching the forums. Your post here is in the Marketplace support forum. This is why I asked. The two parts of the site are separate and operate with their own search engines.

We have had a few problems with the forum search engine lately but are working to restore it.

The best luck I have had with to unstick a stubborn carb, or any other engine part for that matter, is to soak it in denatured alcohol for an hour or two. The alcohol will penetrate the solidified oil from the fuel and allow the barrel to start rotating. Be sure to remove any plastic parts first though as they may become brittle or even fall apart during the soak. If that does not work, placing the carb in a toaster oven (450F) for about 5 minutes is another trick. Be sure to completely flush the alcohol out first or it may ignite. Barring those to methods, you may want to post a question in the Engines discussion forum for other suggestions.
